Underwriting Methodology & Mathematical Formulation
Our calculation algorithms strictly adhere to institutional lending conventions, CFPB disclosure rules, and statutory IRS definitions:
- Standard Annuity Formula: Monthly payment M = P * [r(1+r)^n] / [(1+r)^n - 1], calculating exact interest and principal allocations down to the penny.
- Zero-Roundoff Double Precision: Computations execute using standard IEEE 754 floating-point and integer math to match commercial bank loan documents.
- Sensitivity Analysis: Real-time stress testing against interest rate fluctuations, vacancy rate increases, and balloon maturity horizons.

What is a DSCR loan and how does it work?
A DSCR (Debt-Service Coverage Ratio) loan is a non-QM mortgage for real estate investors. Rather than verifying personal W-2 tax returns or personal debt-to-income (DTI) ratios, lenders qualify the loan based solely on the property's expected or actual rental income compared to its monthly PITIA (Principal, Interest, Taxes, Insurance, HOA).
What is the minimum DSCR required to qualify?
Most non-QM lenders seek a DSCR of 1.20x to 1.25x for competitive rates and up to 80% LTV. However, many lenders offer sub-1.0 or no-ratio DSCR loans down to 0.75x or even 0.0x for properties in high-appreciation markets or short-term rentals, typically requiring a 25% to 30% down payment.
How is the DSCR ratio calculated?
DSCR = Gross Monthly Rental Income / Monthly PITIA. For example, if a rental property generates $3,000 per month in gross rent and the total monthly payment (PITIA) is $2,400, the DSCR is $3,000 / $2,400 = 1.25x.
Can I use an LLC or corporate entity for a DSCR loan?
Yes. In fact, most DSCR lenders encourage or mandate that properties close in the name of an LLC, LP, or corporation to shield personal assets and facilitate multi-partner syndications.
Are short-term rentals (Airbnb and VRBO) eligible for DSCR financing?
Yes. Many modern DSCR lenders allow projected or historical short-term rental revenue verified through AirDNA Rentalizer or 12-month platform operating statements to underwrite debt service.
What is the difference between Interest-Only and 30-Year Fixed DSCR loans?
An interest-only (I/O) DSCR loan lowers your mandatory monthly payment during the initial 5 to 10 year period by eliminating principal payments. This significantly boosts your monthly DSCR ratio and maximizes immediate cash flow.
